user32/edit: Handle IME composition result string only when EIMES_GETCOMPSTRATONCE is set.

If EIMES_GETCOMPSTRATONCE is not set, WM_IME_COMPOSITION with LPARAM set to GCS_RESULTSTR should be passed to the default window procedure according to MSDN. Fix some windows based on edit control not being able to input Chinese. Signed-off-by: Zhiyi Zhang <zzhang@codeweavers.com>
